## NurbsSurface class

[`NurbsSurface`](/3d/python-net/aspose.threed.entities/nurbssurface) is a surface represented by [NURBS(Non-uniform rational basis spline)](https://en.wikipedia.org/wiki/Non-uniform_rational_B-spline),
A [`NurbsSurface`](/3d/python-net/aspose.threed.entities/nurbssurface) is defined by two [`NurbsDirection`](/3d/python-net/aspose.threed.entities/nurbsdirection)[`NurbsSurface.u`](/3d/python-net/aspose.threed.entities/nurbssurface#u) and [`NurbsSurface.v`](/3d/python-net/aspose.threed.entities/nurbssurface#v).
The w component in control point is used as control point's weight whatever the direction's type is a [`CurveDimension.TWO_DIMENSIONAL`](/3d/python-net/aspose.threed.entities/curvedimension#TWO_DIMENSIONAL) or [`CurveDimension.THREE_DIMENSIONAL`](/3d/python-net/aspose.threed.entities/curvedimension#THREE_DIMENSIONAL)
